docker-compose build and docker build lead to different IDs #883
Description
When building containers for my project I noticed that, even if I build from the same Dockerfile, fig and docker build different image IDs in the end.
I also tried to use the same tag, but the images still were different.
Built with fig:

ec26eedffc59 and 8fecc44750ee is the same file, but added with different IDs.
Is there anything I've overlooked or is this a bug?
Using fig 1.0.1 docker 1.3.2.
